Windows Server 2016

Windows Server 2016 is the successor to Windows Server 2012 R2. Built upon the same core code as Windows 10, Windows Server 2016 brings enhancements in security, servicing, and connectivity. A particular focus on this release was hybrid-cloud scenarios, and has close ties to Azure and other Microsoft cloud initiatives. This does not detract from the many improvements that are available for on-premises-only deployments

Windows Server 2016 comes in Datacenter, Standard, and Essentials editions, and for servicing, has adopted windows 10's cumulative model. The new nano-server install is designed to be remotely managed and is designed to be kept current through continuous feature updates. The full GUI install operates similarly to windows 10's "Long Term Servicing Branch" (LTSB) model with cumulative security updates.

Windows Server 2016 has also shifted from a per-processor-and-CAL licensing model to a per-core-and CAL licensing model. This brings Windows Server's licensing more in line with Microsoft's other products and makes hybrid-cloud license planning easier as well.

This article demonstrates DFS namespace and replication group accidental deletion recovery. DFS-N and DFS-R configuration are stored with active directory. Few precautionary measures will enable DFS-N and DFS-R recovery either from DFS native tool (dfsutil) or active directory.

If user does save previous version of file from VSS, the restored previous version gets replicated to DFSR partner

If VSS is enabled on both replicated partners, the last restored file will win and replicated to all partners

Note that since VSS copy is server specific it will not get replicated across DFSR partners
The VSS versions of same file on both servers can be different based on time difference of VSS snapshot is triggered
If VSS snapshot is triggered on all replicated members at same time, you would get previous version data similar on all members, note that this is workaround as VSS copy is separate for every member

I hope this is clear

The 7 Worst Nightmares of a Sysadmin

Fear not! To defend your business’ IT systems we’re going to shine a light on the seven most sinister terrors that haunt sysadmins. That way you can be sure there’s nothing in your stack waiting to go bump in the night.

In this article I will cover Microsoft DFSR major issues and their resolution. These issues can occur during initial deployment or post-deployment. The resolution for each problem is available on the internet generally in standalone posts. I have tried to present them here collectively and detailed.

What are some good heuristics when considering the ratio of total Guest vCPUs to Host Physical Cores(ignoring HT/SMT); 2:1, 3:1?
The more involved followup might be how to measure core contention on a Hyper-V Host

Also when does core count matter more vs frequency, I guess the answer is workload dependent.
20 Cores @ 2.5Ghz (50k Ghz)
16 Cores @ 3.7Ghz (59.2k Ghz)

Microsoft used to have a set of values for VM counts depending on processor core count and GHz. Those recommendations have essentially been sidelined due to the fact that CPU is pretty much not the bottleneck anymore.

That being said, we go for GHz before core count as a rule because it's just that much faster to get the smaller vCPU count VM's threads through the CPU pipeline.

And finally, a wide core count would indeed be needed for multi-threaded applications like SQL to get through the pipeline as soon and as wide as possible.

Windows Server 2003 introduced persistent Volume Shadow Copies and made 2003 a must-do upgrade. Since then, it's been a must-implement feature for all servers doing any kind of file sharing.

I would add that you REALLY SHOULD store snapshots on a separate volume. The reason is that Windows may DELETE your snapshots stored with the parent volume during high disk IO. Imagine you have a large restore to do on your file server, so you do a smaller test restore first. It works, but the act of restoring creates so much IO that the other snapshots get deleted...the same snapshots you were about to use to restore from. Ouch! I have heard about it happening. It's the first best practice Microsoft lists.

Actually, I do recommend this...
"BUT WAIT! Before enabling, if you want to place your copies on a different volume or better still different physical disk (recommended for heavily used file servers), you need to click on the settings button before any copies are created (enabling a volume will instantly create a copy)."

In previous parts of this Nano Server deployment series, we learned how to create, deploy and configure Nano Server as a Hyper-V host. In this part, we will look for a clustering option. We will create a Hyper-V cluster of 3 Nano Server host nodes with Storage Spaces Direct on it.

Hi,

I'm trying to connect a virtual machine (on ESXi 6) to Internet. I have seen most people can do it just with install vmware tools, but it doesn't work for me. Can you help me to configure it? I have an ESXi 6 server and I have two Vmachines (ubuntu and windows), neither of them are connected to Internet. Windows VM has a dhcp configuration (I'm not sure if it's ok, I supouse vStwich gives Internet...) How do I have to configure the vm? or the server? or the vSwitch?
Thanks
